Qs 1 If "oinstall" is the primary group of the Oracle Owner i.e. all the
10gR2 Oracle software binaries are owned by "oinstall" group, then what
is the use of the "dba" group in RAC?
Qs 2 Is "dba" a reserved word and does any Unix user belonging to this
group automatically have "DBA" role grants/privileges in 10gR2 / Solaris
Qs 3 Is it advisable to use "oinstall" as the primary group of the
ORACLE Owner in place of "dba" as advised in the Oracle Manuals for 10g
From the Oracle Manual:-
To create the oracle user, enter a command similar to the following:
# /usr/sbin/useradd -u 200 -g oinstall -G dba[,oper] oracle
In the preceding command:
The -u option specifies the user ID. Using this command flag
is optional, as you can allow the system to provide you with an
automatically generated user ID number. However, you must make note of
the oracle user ID number, as you require it later during
The -g option specifies the primary group, which must be the
Oracle Inventory group--for example, oinstall
The -G option specifies the secondary groups, which must
include the OSDBA group, and, if required, the OSOPER group. For
example: dba, or dba,oper
Qs 1 - If Oracle 10gR2 Binaries (NON-RAC type installation) already
exists on the Machine, in Order to do a NEW RAC setup using the Same
machine as 1 of the nodes, is it advisable to again install respective
RAC type Oracle 10gR2 Binaries into another ORACLE_HOME path?
If YES, should any changes me made to the /var/opt/oracle/oraInst.loc
file to prevent the NEW Oracle RAC Binaries installation from knowing
about the previous NON-RAC Oracle installation?
